Description

A Pressure-Volume-Temperature diagram for substances that expand upon freezing (such as water). On the labeled diagram, axes and phases are labeled, though it may be difficult to read the phases.

I've found that this diagram is quite helpful in thermodynamics. Although it's not completely accurate, it's close enough that you should be able to tell what it's supposed to look like. (The tiny erroneous edge along Solid+Liquid never shows up in a print, as far as I can tell, but Inventor just couldn't remove it.)

Print Settings

Printer: M3D Micro

Rafts: Doesn't Matter

Supports: No

Resolution: 0.3 mm

Infill: 5-10%

Notes: For the sake of the text, print it with the pressure axis vertical. This also gives the fastest print time.

Bro, your diagram is wrong... very sad

What do you mean, wrong? I used a diagram similar to this one (minus Ice III) for reference. http://berkeleyphysicsdemos.net/node/368 I also took the diagram to my thermodynamics professor when I was in college, and he's the one that told me to write "Fluid" instead of "Gas" in the area above the triple point.
